year 2000 restored to leap year in new calculation. common, divisible by 400, will be later than that.

I have recalculated calendar year divisibility corrections to push back the 2000 year correction. It's actually a better set of corrections than the original one. It achieves the same fit in 7 corrections instead of 12. I still won't reveal any of them though until I get an escrow agreement at an acceptable price.

I have yet to address the slowing of the earth's rotation, which decreases the ratio of days per year over time.
